Portables are the best for this, imo. Steam Deck or a used 3DS are my choices. The latter is easy to mod and play all sorts of games including the gigantic DS/3DS library.
I find both systems clutch for the suspend function. Lets you pick right back up where you were. I will say the 3ds is much better at this with clamshell design that suspends on closing the lid and it’s battery life in suspend is fantastic!
I also find stress relief games. Mindless 3rd person action games for me. Mad Max was great because I could drive around picking fights or crashing stuff. The Batman Arkham games and the Shadow of Mordor games are other great examples for me. I have not found any relaxing “cozy” games that work for me. Nothing has really grabbed my attention enough to stick with.
These are maybe not what some would consider beautiful, but I love the variation in art styles and how they can be beautiful while either being simplistic or retro-inspired. All but Sea Of Stars were very cheap during the Steam Summer sale or in a Fanatical bundle that may or may not still be available right now.
I work from home, so the last thing I want to do on my leisure time is sit at the same desk I’ve sat at for the last 8 hrs. So I lounge on the couch and play through my huge steam deck library. It is not a cheap device, to be sure. But I felt it was absolutely worth it for me.
